SUSPENSION-CLAMP.

Specification of Lc tters Patent.

Application filed AugustZO, `1910. Serial No. 578,221.

Another object is to provide an improved,

suspension clamp having a `I novable clamping member and adapted to have the conductor or cable installed in position without detaehing the movable clamp tl'ieretrom.

Other and further objects will appear in the specification and be specifically pointed out in the claims, reference being had to the accompanying drawings exemplifying the invention, and in which- Figure 1 is a side elevation of a suspension clamp constructed in accordance with this invention, and showing a conductor cable in position therein. Fig. 2 is an end elevation of the clamp shown in Fig. 1. Fig. 3 is a top plan view of the same. Fig. #1 is a section on the line IV-IV Fig. 1. Fig. 5

is a vertical longitudinal section of a modiication of the invention. Fig. (3 is a section on the line VI--VI, Fig. 5. Fig. 7 is a section on the line VII-VH, Fig. Fig. 8 is a detail section corresponding to F ig. 7, showing a further modification of the snspension clamp.

In the embodiment shown in the drawings, the clamping device comprises a main body member, a movable clamping member. and means interengaging between said members whereby they may be drawn into clamping engagement with a cable or other conductor 1. The main body member is pret erably constructed as an integral casting comprising aA pair of oppositely opening hooks or rooved saddles 2, 3, elongated longitudinal y of the cable or conductor l to provide an extended bearing surface for said conductor. The Shanks 4 and 5 of' said hooks or saddles 2 and 3 are disposed re-v Patented Sept. 22, 19

mousing, each for the other, as shown most clearly in Fig. Il. -Thus the conductor 1 when elevated above the upper edge otl the lip G ot the grooved saddle or hooi: 2, would be held against lateral displacement there- `from by means of the shank 5 ot' the other hook or saddle. Iarh ot! the hooks or saddles is provided with a groove of substantially thc same curvature or `formation' the conductor or cable carried thereby. the outer ends ot' said saddles being detlected downwardly respectively as shown at 7 and 8 in Fig. 1. The main body casting is provided ,intermediately ot the saddles 2 and 3 with a vertical-sloom which permits said main body member to be introduced over the cable or conductor 1 in a plane trans-- verse thereto until the upper edges of the lips 6 and 10 ot' the saddles 2 and il are below said cable 1, when the body member may be rotatedabout an axis transverse to the cable 1 until the lateral faces of the shanks'lt and 5 abut against the `able l, when said body portion may be lifted to causevthe cable to seat within the grooved saddles, as shown in Figs. 1 and 2. i

In order to provide suitable means for movably supporting the main body of the clamp in such a manner that it` may bc oscillated about an axis transverse to the cable l, the upper end ot the body casting is provided with a gltibnlar head tlA provided with a socket 12 for the reception of the flattened circular lrcad i3 ot an insulat ing pin 14, the upper wall of the globular portion 11Y being perforated at 15 Afor the reception of the pin 14. The perforation 15 is extended to connect with an opening 1G in the lateral wall o't5 the globular portion 1l, said opening ttl being suflicientlv large to permit the introduction ot the flattened head 13 of the pin let. ln order to hold the tlatvtened head 13 against displacement lrom itz-l socket, a Cotter' pin 1T is introduced through a perforation in the globular portion l1 to hold itin its raised position, as shown in Figs. .1 and 2.

Means for clamping the cable or conductor 1 to the saddles 2 and 3 is provided by the clamp bar 18. which is slidabtiY mounted between thc shanlts 'tand 5. said clamp bar being provided on its lower edge, as shown in Fig. 4, `with a circular groow` 19. Said block is, moreover, preferably provided with a downwardly protruding` titl mit the int portion 19 opposite the slot 9, so that when the block 18 is drawn down upon the c011- ductor l, it is depressed, as sho-wn in Fig. l, so as to secure it more firmly within the suspension clamp. In order to provide means for drawing down the block 18 upon the conductor 1, it is provided with a pair oi' perforations for the reception of bolts 20 and 21, said bolts being preferably bent at right angles, as shown best in Fig. 1-, to 'enable the Shanks of the bolts to be housed in recesses Q2, 23, formed in the walls of the shank portions d and 5 respectively. of nuts 24 upon the lower threaded ends of the bolts 2O and 21 serve to draw the clamping block 18 into clamping engagement with the conductor l.

Referring now to the embodiment shown `in Figs. 5, 6 and Q the main body casting ot' the suspension Aclaxnp is similar to the embodiment shown in Figs. l to 4C inclusiva with the exception that said casting is provided with a slotted head 25, the slot 26 in which is adapted to receive a. tongue 27 at the lower end oit' a depending suspension link or bar 28 which may be supported from above in any desired or suitable manner. The tongue and slot connection between the slotted head` 25 and the bar and link 28 is completed by a pin 29 which pivotally supports the suspension clamp from said bar or link.

As shown in Fig. 7, the clamping bar 18 is beveled along its upper edge at 30 to provide an abutting surface tor the bolt heads 3i oi' the bent clamping bolts 20.

According to the embodiment illustrated in Fig. 8 the clamping bolts are perfectly straight and the hookshank portions of the body casting are provided with bolt sockets 32 which projectlaterally from the body casting, the end walls ot said sockets being pertorated for receiving the bolts. For this embodiment, the clamp bar 18'( is beveled more sharply above but in other respects is substz'intially the sance as the clamp bars shown the other embodiments.

4What claim is :M
